King's Arena is a weekly match-up where players can win various rewards including powerful Battle Cards. Players are matched up against other players in a 2 vs 2 hero duels. The opponent's heroes are controlled by the AI meaning that the matches are not real-time Player vs Player (PvP) matchups.
For each battle, players are able to choose from 3 different sets of 2 heroes to play against in order to earn points. The 3 sets of heroes are worth 5, 8, and 12 points if you win against them. There is also a winning streak that is recorded to give a increasing amount bonus points for each consecutive win. Each win adds 1 point to the win streak bonus, and all bonus points are lost after losing a match or if the win streak timer expires. Each win restarts the win streak timer at approximately 6 minutes.
Arena matchmaking uses a complex ELO ranking system. The 5, 8, and 12 point matchups are supposed to be players with a lower, equal, and higher ELO that yourself. In the current system it is possible to run out of 12 point matches by raising your ELO. Losing to hard (12 point) matchups will lower your ELO less than losing to easy (5 point) matchups. If you lower your ELO enough 12 point matches will reappear.
Each King's Arena is available for 6 days and 23 hours starting 1 AM GMT Tuesday morning or 8 PM ET/ 5 PM PT Monday night. After the conclusion of the event there is a one hour break in which the next arena is advertised but no arena matches can be played. King's Arena is unlocked at Fame 6.
During each season of King's Arena there are two sets of rewards that are offered to players based on how many points they earn and how they place compared to other players.
General arena rewards range from 5 to 785 points and usually include at least 1 Rare Battle Card
In the King's Arena your amount of points earned are compared against other players and ranked.
